MEASURING-MACHINE.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed March 16, 1917. Serial No. 155,293.

To all whom it may concern:

Be it known that I, GEORGE FELIX EASON, a citizen of the United States,residing at Manning, in the county of Dallas and State of Arkansas, haveinvented certain useful Improvements in Measuring-Machines, of

which the following is a specification, referquired length and suchlength accurately determined, thereby obviating the necessity of themeasuring of the rope by hand with a rule or other like device.

Another object of the invention is the provision of a machine of thischaracter wherein the construction thereof is novel in form so that thesame can be readily adjusted relative to the cross sectional size of therope to .be measured and also to avoid any possibility of the slippingof the rope durmg the letting out thereof and the measuring operation ofthe machine. a

A further object of the invention is the provision of a machine of thischaracter which .is extremely simple in construction strong, durable andeflicient in operation and inexpensive in manufacture.

Other objects will be in part obvious and in part hereinafter set forth.

The invention accordingly consists in the features of construction,combination of elements and arrangement of parts which will beexemplified in the construction hereinafter described, and the scope ofthe application of which will be indicated in the appended claims. I Inthe accompanying drawing:

Figure 1 is a top plan View of the machine constructed in accordancewith the invention;

Fig. 2 is a bottom plan view thereof;

Fig. 3 is a sectional view on the line 33 of Fig. 1;

Fig. 1 is a sectional view on the line 4-4 of Fig. 1;

Fig. 5 is a vertical longitudinal sectional View through the machine.

Similar reference characters indicate corresponding parts throughout theseveral views of the drawing.

Referring to the drawing in detail, the measuring machine comprises amain support A, preferably in the form of a board or plate, either in asingle piece or made in sections, the said board or plate being adaptedfor attachment to a counter or other stationary element, and is formedwith an elongated slot 5, which is disposed. longitudinally therein andopens through one end of the same. Within this slot 5 is arranged a feedroller 6 fixed to a journal 7 having its bearing in the support A, andlying transversely of a recess or chamber 8 formed in the support A atone side of the slot 5, the journal 7 within the slot of the chamberbeing formed with a worm screw 9 meshing with a worm gear or wheel 10which is arranged within the chamber or recess 8 and has its shaft 11suitably journaled in the support A and in a dial plate 12 which isfastened upon the top of the support A to close the recess or chamber 8,and on the outer face thereof, concentrically of the shaft 11 hasprinted or otherwise marked a measuring scale 13, the up per end of theshaft being reduced to form a shoulder 141 for a purpose presentlydescribed.

Cooperating with the feed roller 6 is a guide roller 15, the same beingjournaled within a forked bearing 16 which is formed with a screwthreaded stem 17, and this hearing 16 is movable within the slot 5 so asto regulate the position of the guide roller 15 relative to the feedroller 6, these rollers being formed with peripheral grooves 18 for therope which is adapted to be trained therebetween, while on oppositesides of the grooves, at the peripheries of the rollers, arecorrugations 19 Which prevent the slipping of the rope or the working ofthe same from the grooves in said rollers when the machine is inoperation.

The stem 17 of the bearing 16 is slidable through a web 20 separatingthe slot 21 from the slot 5, and this slot 21 is occupied by anadjusting nut 22 which is threaded on the screw stem 17 so that thebearing can be manually adjusted for the proper positioning of therollers 6 and 15 relative to each other.

On the reduced end of the shaft 11 is carried a 'pointer or indicatorhand 23 which rests against the shoulder let and is frictionally held inadjusted position through the medium of a resilient washer 24: which isretained in place upon the shaft by across pin 25 mounted therein, andthis pointer or hand 23 cooperates with the indicia of the scale 13 sothat an observer can accurately determine the measurement of the roperelative to length. l 1 s From the foregoing description, taken inconnection with the, accompanying drawing, the construction andoperation of the herein described measuring device will be readilyapparent and, therefore, a more expin, said grooved wheel being formedwith opposing v spur side edges flanking, said groove, a stem upon saidbearing, said base- 'board being formed with a longitudinal borecommunicating with said slot, and with an opening registering with theother end of said bore,and also with another opening intersecting thelength of said bore, a toothed wheel for actuating said stem and fittingsaid last-named opening, the 'free end of said stem adapted toridewithin the first opening, a fixed grooved wheel journaled within theedges 'of -said slot in advance of said bearing, an indicator on saidbaseboard, and a movable pointer on said indicator controlled by thelast-named grooved wheel.

' 2. In a device as described, in combination, a base-board,.said boardformed with acountersunkrecess, a spindle rotatably mounted in saidbase-board below said countersunk recess, a worm wheel upon said spindleinsaid recess, said board being also formed laterally of said recesswith a longitudinal slot, and "having a transverse passage registeringwith said recess and .also with said slot, a pin-bridged across saidslot and engaged transversely within said base-board, a; worm onsaidpin'meshing with said worm wheel anddisposed snugly in said passage, awheel upon said pin rotating in said slot, a' platesecured uponfsa'idbaseboard and "inscribed with a "circular series'of indications, saidspindle projecting above said plate, and a pointer carried by saidprojecting end of said spindle and engaging said plate to mark off saidindications.

3. In a device as described, in combination, a base-board formedjwithan"'elongated slot, a pin spanning said slot atone end of saidbase-board, a grooved wheel fiXed "upon said pin so as to revolve withthe same, a longitudinally-movable carriage in said slot, a groovedwheel journaled' in said carriage, means whereby said carriage 1sactuated so as to move toward and from the first-named grooved wheel,means for holding said carriage against displacement as it slides insaid slot.

In testimony whereof I aflix my signature. "75
